Gents, in response to recent posts...
Rastaman, here's a pic of my tie down arrangement when I was still planning to keep Argo a truck camper. It's a SS marine bow eye bolted thru the base of the jack plate. It worked quite well and, at 2500 pound SWL, I had a high degree of confidence in it's ability to keep everything together. I like the idea of distributing the force thru two bolt/nut attachments rather than a single eyebolt. My only advice would be to be certain your mounting spot will allow easy attachment of the actual tie down.

Silver, I have high hopes for the aluminum interior corners. Here's a pic of the construction paper stage of the layout. At this point I was laying out on the plastic liner. It ended up being much more accurate to lay out on the ribs after I'd removed the liner. But you can get the idea here...
As for the Argo process, I replaced the aluminum frame channel that ran across the truck chassis because they were deflecting too much under the load of Argo. We made steel cross pieces using heavy wall rectangular tubing. It's plenty strong and stiff. I kept the aluminum channel that runs lengthwise under the actual box of Argo. I just set Argo onto the newly engineered frame yesterday. No deflection now.
I have now begin the layout of the side storage box assembly. You may recall that this old customized rig in SoCal was the basic inspiration:
I was feeling daunted by the prospect of the design and layout. I called truck service body builders on the west coast to see if I could get one built. Finally I just bit the bullet and started mocking up what I want. Here are two approaches:
This is the straight back approach and conforms to the line of the bottom of the bustle. I'm trying to keep the bustle because I customized it to create a very nice fiberglass gray water tank inside it. But this line wastes a lot of potential storage, which is woefully lacking in Argo, so I brought the box down to the same bottom elevation as the cab:
This is a more conventional use of space and gives me lots more room for an eventual layout something like this:
I've studied the stock doors on the outside of Argo to come up with a door construction detail for these compartments. I found that propane and fridge doors were made of .037" stock. The water heater door was made of .060" stock. Thicker will certainly be better for my storage doors. I'm going to build the water tanks into the curved front ends of the storage areas. I reckon I can get about 30 gallons on each side. This offers the advantage of the water weight being low and in the middle of the rig.
I'm going to be glad to get these compartments built and installed so I can bolt Argo to the truck and get on with the interior. If I'm going to make it to Muley Point this summer, time is of the essense!
